First product to undergo Technology Partnerships

A Technology Partnerships study has been announced to evaluate the safety benefits of a solar-powered traffic signage system designed to minimise crashes on horizontal curves in the US. Part of the US FHWA Highways for Life initiative, evaluations will test the effectiveness of innovative road infrastructure safety technologies that are fully developed and market ready, but have had little use on US roads.

Tapco's sequential dynamic curve warning system will be evaluated for two years in several US states
A Technology Partnerships study has been announced to evaluate the safety benefits of a solar-powered traffic signage system designed to minimise crashes on horizontal curves in the US. Part of the US 831 Federal Highway Administration Highways for Life initiative, evaluations will test the effectiveness of innovative road infrastructure safety technologies that are fully developed and market ready, but have had little use on US roads.

Although horizontal curves make up a small percentage of total road miles, they account for 25 per cent of all highway fatalities with the majority of crashes on curves involving lane departures. US company Traffic and Parking Control Company (989 TAPCO) has developed the sequential dynamic curve warning system which consists of a series of solar-powered, LED-enhanced flashing signs that are installed throughout a curve. Approaching vehicles, sensed by radar or other ITS device, trigger the controller that wirelessly activates the LED signs to flash sequentially through the curve to warn speeding drivers to slow down. The two-year Technology Partnerships field study will evaluate the effectiveness of the system in reducing vehicle speeds and in reducing the frequency and/or the severity of curve-related crashes. Participating State DOTs include Missouri, Texas, Washington, Wisconsin and Colorado.

    Innovative parking initiatives on the US Pacific Coast. David Crawford reviews. Californian cities are leading the way in trialling new solutions to their endemic parking problems. According to Donald Shoup, a professor of urban planning at the University of California in Los Angeles, drivers looking for available spots can cause up to 74% of traffic congestion in downtown areas. One solution is variable, demand-responsive pricing of parking.

    David Crawford looks at technologies for better emergency medical service delivery. Emergency medical services (EMS) play key roles in transporting, or bringing treatment to, patients who become ill through medical emergencies or are injured in road traffic accidents (RTAs). But awareness has been rising steadily, in the US and elsewhere, of the extent to which EMS can generate their own emergencies. The most common cause is vehicles causing or becoming involved in RTAs, as a result of driving fast under pr

    An independent analysis carried out by engineer Dave Finney of Thames Valley, UK speed camera data has found an increase in injuries after the devices were installed. The analysis, to evaluate the effect of fixed speed cameras on the number and severity of collisions at the sites where they are installed, was carried out on two groups of sites. One group includes all fixed speed camera sites in the Thames Valley area (covering Oxfordshire, Buckinghamshire and Berkshire) that were active at the start of 2
